Comparison
Magnesium L-Threonate vs CoQ10
Magnesium L-Threonate
MIT-developed magnesium that crosses the blood-brain barrier. Shown to enhance synaptic density and reduce 'brain age'.
CoQ10
Mitochondrial electron-transport cofactor. Naturally declines with age. Ubiquinol form is the active reduced state.

The comparison in plain English
Auto-generated from dataMagnesium L-Threonate and CoQ10 are both in the neuroprotective category respectively. Magnesium L-Threonate MIT-developed magnesium that crosses the blood-brain barrier. CoQ10 Mitochondrial electron-transport cofactor.
Bottom line
Magnesium L-Threonate (evidence B, safety 5/5) has a stronger evidence base than CoQ10 (evidence A, safety 5/5). Magnesium L-Threonate has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose Magnesium L-Threonate if
Magnesium L-Threonate is the better fit when your goal aligns with its mechanism (L-threonate is a sugar-acid carrier that uniquely enables magnesium to cross the blood-brain barrier in meaningful quantities — most oral magnesium forms (oxide, citrate, glycinate) raise serum magnesium but not central magnesium) and the dose range (1000–2000mg) suits your protocol. Half-life is 6h.
Choose CoQ10 if
CoQ10 is the better fit when your goal aligns with its mechanism (Cofactor in the mitochondrial electron transport chain at complexes I, II, and III — moves electrons between dehydrogenases and complex III, enabling ATP synthesis) and the dose range (100–300mg) suits your protocol. Half-life is 33h.
